E. Application of solvent cement
•
Apply solvent cement evenly and quickly around
outside of pipe at a width a little greater than the
depth of the fi tting socket.
•
Apply a light coat of cement evenly around the inside
of the fi tting socket. Avoid puddling.
•
Apply a second coat of cement to the pipe end.
• Cans of cement and primer should
be closed at all times when not in
use to prevent evaporation of
chemicals and hardening of cement.
• They are also very flammable and
should be kept away from heat or
flame.

F. Joint assembly
Working quickly, insert the pipe into the fi tting socket
bottom and give the pipe or fi tting a 1/4 turn to evenly
distribute the cement. Do not continue to rotate the
pipe after it has hit the bottom of the fi tting socket.
A good joint will have suffi cient cement to make a
bead all the way around the outside of the fi tting hub.
The fi tting will have a tendency to slide back while
the cement is still wet so hold the joint together for
about 15 seconds.

G. Cleanup and joint movement
Remove all excess cement from around the pipe
and fi tting with a dry cotton rag. This must be done
while the cement is still soft.
The joint should not be disturbed immediately after
the cementing procedure, and suffi cient time should
be allowed for proper curing of the joint. Exact drying
time is diffi cult to predict because it depends on
variables such as temperature, humidity and cement
integrity. For more specifi c information, you should
contact your solvent cement manufacturer.
